As much as this question came up when the KTouch was released you'd think at least one or two of the tech blogs that were at the press event would have checked this out during the hands on, but so far I can't find any mention and it doesn't appear there's a users manual up yet on Amazon.

I just saw a video on YouTube. It does have landscape.

It was the one by cNet. It shows the menu and the landscape option is there.

I was in bed playing YouTube reviews on my phone. I was actually trying to annoy hubby because he didn't share my enthusiasm about the Paperwhite. So I was making him listen to the reviews hoping he see the beauty of the device when I just happen to glance and thought I saw the option Landscape Mode on a menu shot. I squealed making him jump. I backed up the video and paused it and sure enough it was there along with several other menu options I haven't seen before.

I was using Tapatalk at the time so I couldn't post the link but here's the review that shows that shot.

I posted a thread about this a while ago. The Verge had this story up earlier today how all of the Kindle Fire tablets will be ad only versions.

Someone on the Amazon forum (generally a wretched hive of scum and villainy, I know, but occasionally useful information pops up) has spoken to customer service who's said there will be an opt-out option. FWIW.
